Paper manufacturing structure particularly for detaching a web from a wire

DETAILED DESCRIPTION What is claimed is: 1.
A method for operating a paper manufacturing machine wherein a web is detached from a forming wire loop and conducted to a press section of the machine by a transfer felt, comprising the steps of: conducting the web carrying forming wire into engagement with a first sector of a detachment transfer roll situated inside said wire loop over which the direction of travel of the web substantially changes; conducting the transfer felt in a relatively dry condition into engagement with the web over a second sector within said first sector of the detachment transfer roll, said transfer felt also functioning as a pressing felt partially operating in at least one of the press nips in the press section; providing a press suction roll contiguous with the detachment transfer roll defining a transfer nip at the second sector through which the transfer felt is conducted and in which the detachment of the web from the wire and transfer to the felt occurs; the press suction roll being provided with at least one external suction compartment for applying suction from the suction roll in said transfer nip and at least one of the press nips; applying suction from said press suction roll to said web in the transfer nip and in at least one of the press nips; detaching said web from said forming wire and transferring it to said felt under the relative prolonged action of centrifugal force acting on the web by virtue of the change of direction of the web over at least a portion of the first sector of the detachment transfer roll and simultaneous adhesion forces which cause said web to adhere to the outer side of the felt, said web detachment being further facilitated by said application of suction in the transfer nip from the suction roll; and transporting the web on the transfer felt from the transfer nip to the first dewatering press nip of the press section.
2.
A method as recited in claim 1 wherein during the step of transporting the web on the transfer felt from the transfer nip to the first dewatering press nip of the press section, the web is supported on the felt by at least the suction from the press suction roll and including the further step of transporting the web on the transfer felt from the first press nip to a second dewatering press nip with the web being supported on the felt by at least the suction from the press suction roll
